针对靶标场等摄影任务受轨道维持影响大的现状, 提出基于摄影任务的轨道维持策略。分析了卫星轨道特性和轨道维持对重要摄影任务的影响, 提出利用邻轨搭接特性对摄影区域完成两次摄影的方法。通过某靶标场摄影试验, 比较分析得到最优摄影方案, 验证了本文方法的可行性。同时完善卫星轨道维持策略, 作为卫星实施轨道维持的重要参考依据。

This paper presents the strategy of Mapping Satellite-1 orbit maintenance based on photographic mission, for the status of the considerable impact of orbit maintenance upon photographic mission. This paper analyzes the orbit characteristics and the impact of orbit maintenance upon photographic mission, and presents one method of getting the photographic mission twice by overlap characteristics of the adjacent tracks. An example application is given, and the result confi rms the feasibility of this method. In addition, this paper improves the strategy of orbit maintenance by analyzing photographic mission.
